Nate,
getting condensation means: There's a water leak somewhere in your headlamps. This leak let water inside the lens, forming a clouding inside the assembly and looks kinda foggy. Condensation appears either of a leak outside of your headlamps, or it can happen when you clean your headlamps by using with high pressure. Also the best seal can not resist such high pressure of water, you know? Just in case you did it

How To Clean Off Condensation
You have 3 ways to get rid off this condensation...

1. Temporarily Solution
Open the headlamp plastic cover(s) and remove the bulb(s). Put your car in your garage and wait 24 hours. The condensation disappears itself after this period of time. Unless the problem of water leakage is resolved, though, this will happen again and again. You can see, this solution is temporarily and sometimes not the the best. But it can help when you know, there's absolute no leak.

Just a side note: Please check the small rubber drain tubes on the bottom of your headlamps. All lamps have it, except tail light lamps. It is rarely possible they got clogged. It can happen but very rare. That means, the condensation will never go out itself. Just a thought.

2. Clean Solution
To clear up the inside of the headlamps, it must be removed and place inside a warm, dry environment for a minimum of 24 hours (inside the house is fine). Take out the headlight and shake/pour any water out that you can. After that, put the headlight in a small room with a dehumidifier on full blast overnight. All condensation will be outta there by the morning. After that you would go ahead and apply the silicone sealant.

3. Repair Solution
Take a pail of water and pour any water on your headlamps. If you see water comes into the lamps, then you have a serious seal problem. This problem is very easy to fix. It's just the silicon from when the factory sealed them has some how opened. I'd suggest taking them out and using the Oven Method to clean the inside and reseal them with a waterproof sealant.

Mike, Why would Lexus put the drain tube on the top? How's it going to drain?(not that you designed it or anything, I was just curoius...)

On top? Yes? Where? I didn't notice this. Or maybe that pic is kinda upside-down? You know what? I'm so clueless. And if it's true and I believe you: It makes really no sense to put the drain tube on the top -Mike

Sorry, my bad. I looked again and there are three on each, two on the bottom and one on the top. when I asked the question I only looked at the one on the top next to the two adjusting screws.....
